OXYHYDROGEN-BLOWPIPE.

v SPECIFICATION forming part of Letters Patent No. 743,313, dated November 3, 1903.

Application filed $eptembar 3, 1903. Serial No. 171,800. (No model.)

PHY, a citizen of the United States, and aresident of Rochester, in the county of Monroe and State of New York have invented certain new and useful Improvements in Oxyhydrogen-Blowpipes, of which the following is a specification. I

This invention relates to oxyhydrogen-blowpipes, and has for its object to produce ablowpipe of high efficiency that can be cheaply made and easily handled.

In the drawings, Figure 1 represents a side elevation of the burner. Fig. 2 is a vertical section on the line 2 2 of Fig. 3; Fig. 3, a top view, and Fig. 4 a horizontal section on the line 4 4 of Fig. 1.

The base A, which may be formed into a handle, as represented, has two tubes B and C extending through it. The tube Bis for oxygen, and the tube 0 is for hydrogen. A block D is attached to the base A, andthat in turn supports the hydrogen-tubes E E andthe centrally-located two-part oxygen-tube F F. The oxygen-tube F is connected with the oxygen-tube B by the channel Gr through the block D. The hydrogen-tubes E E are connected with the hydrogen-tube C by the channel H and the chamber I in the block D. (Jocks J and K, manipulated by handles L and M, respectively, are adapted to regulate the admission of hydrogen and oxygen to the tubes E and E, respectively.

A cap N is shown upon the upper ends of the hydrogen-tubes E and E, which has an annular chamber 0, into which said tubes E and E open. The cap N has four nozzles Q,

Q, Q, and Q which so direct the hydrogenjets that are blown from them that they are concentrated at a single point.

A tip R is secured upon the end of the ppper section F of the oxygen-tube, that has a central orifice for the discharge of oxygen. The' height of the oxygen-tube is adjusted by extending or retracting its upper section F, as by the ratchet and pinion shown in Figs. 1 and 4.

S is the ratchet, which is represented upon the upper section F, and T is the pinion upon the stem U, having the milled head U.

The operation is as follows: The hydrogen is turned on and lighted. Then the oxygen is turned on, and the tip R is moved until the proper combination of oxygen and hydrogen is eitected.

What I claim is 1. In an oxyhydrogen-blowpipe the combination of a plurality of hydrogen-tubes, so arranged with reference to each other as to concentrate the discharges therefrom at a single point, with an oxygen-tube adapted to discharge oxygen into the hydrogendischarged from said hydrogen-tubes; and means for ex tending and retracting said oxygen-tube; substantially as shown and described.

2. In an oxyhydrogen-blowpipe the combination of a plurality of hydrogen-tubes, so arranged with reference to each other as to concentrate the discharges therefrom at a single point, with an oxygen-tube adapted to discharge oxygen into the hydrogen discharged from said hydrogen-tubes; means for extend ing and retracting said oxygen-tube; and means for regulating the admission of 11ydrogen and oxygen to said tubes respectively.
